Just wondering if anyone has experienced the following, and if so, what do you think is going on:

Been following Paleo with a few extra dairy additions: cream mostly. I've tracked my food on Fit Day for the past 5 weeks. I'm averaging 2500 cals per day: 155 g protein, 100 g. carbs, and the rest fat. This has been part of a progression where I've gradually lowered my carb levels. I'm trying to get single digit bodyfat (presently 18% at 5'7", 170lbs, m, 28yrs). Since January, I've gone from 180lbs at 21%bf to my present condition. So, it's working...slowly.

Anyway, although I've felt good in most respects, this weird thing has been happening for the past two weeks (i.e., as soon as I've dropped below 100g carbs): As soon as my head hits the pillow my heart starts racing and the eyes start twitching. I feel like I'm having a "fight or flight" response. I feel really jacked-up. So, I toss and turn for a couple hours before dozing off. My energy throughout the day, though, is fine. I'm humming!

Has this happened to anyone?

I experimented and the last two days I increased my carb load to about 35% of my diet (more Zone-like Paleo I guess) and I've slept well...

Any thoughts? Should I keep it up with the slightly higher carb load and just decrease my overall caloric load?

I think you answered your own question about whether or not to eat more carbs.....as I would want my sleep.

Why it is happening? Too many hormones and neurotransmitters going on to guess....but listen to your body.

You can get to single digit BF just fine with more carbs, just make sure they are all "real food" (no breads and sugar) and keep calories in check.

It's 2:50 a.m. and I'm up eating grapes. I've been eating 100% Paleo for 1 yr. and from time to time I get a bout of insomnia from too few carbs. Glad I found this thread . This is now my 3rd. night in a row of insomnia.

Haven't had this problem all winter but I just returned to weighlifting from a 3 month lay off for the height of ski season. I backcountry splitboard as a job of sorts.
